Thanks Guys for you help here
running “ apt-get update ” and then “ apt-cache policy certbot ” again I get
root@helpdesk:~# apt-cache policy certbot
certbot:
Installed: 0.26.1-1+ubuntu14.04.1+certbot+2
Candidate: 0.28.0-1+ubuntu14.04.1+certbot+4
Version table:
0.28.0-1+ubuntu14.04.1+certbot+4 0
500 http://ppa.launchpad.net/certbot/certbot/ubuntu/ trusty/main amd64 Packages
*** 0.26.1-1+ubuntu14.04.1+certbot+2 0
100 /var/lib/dpkg/status
I a, a tad confused as the email gives a link How to stop using TLS-SNI-01 with Certbot which say you need to be on 0.28 or higher. To be this running on 0.26.1 to I just need to run the command from the linked page
sudo sh -c “sed -i.bak -e ‘s/^(pref_challs.)tls-sni-01(.)/\1http-01\2/g’ /etc/letsencrypt/renewal/; rm -f /etc/letsencrypt/renewal/.bak”
Running the dry run does seem to suggest it would completed as it does seem to suggest it’s using http
http-01 challenge for helpdesk.pdjitsupport.co.uk
Waiting for verification…
Cleaning up challenges
Would be nice to know though why it will not upgrade to 0.28
Many thanks again
